In november 2005, we purchased the 942 and the installer took 3 recievers (leased) I think i was told I would recieve a 20.00 rebate for each of these...... Did i hear them wrong?
I believe that you receive the $25 credit when you return your owned receivers directly to dish. You would need to call Dish and have them send you the return boxes.
In the case of upgrading to a 622 the credit is $200 for a 921 or 942. Again though it has to be owned.
I don't believe any rebate or credit would apply to leased receivers.
